Separation of halogenated hydrocarbon
Abstract
Abstract PURPOSE:To simply and sufficiently separate halogenated hydrocarbon, by selectively permeating halogenated hydrocarbon by using a fibrous structure having water repellency. CONSTITUTION:A fibrous structure comprising a polytetrafluoroethylene fiber or a polypropylene fiber and having water repellency is used and, by utilizing such a property that said fibrous structure has capacity selectively permeating halogenated hydrocarbon such as trichloroethylene or trichloroethane held under a phase separation state to water, said halogenated hydrocarbon is separated from water. By this method, because liquid permeability is high as compared with a film like microporous membrane, separation efficiency under atmospheric pressure is obtained at a level having no problem from a practical aspect.
